Abstract

This prospective study assessed the role and compared two techniques of paracervical block (PCB) for pain relief during suction evacuation for first-trimester termination of pregnancy following cervical priming with misoprostol. One-hundred and thirty-five women undergoing suction evacuation up to 12 weeks of gestation were randomized into three groups: (a) 5 mL of 1% lignocaine injected at the 4 and 8 o'clock positions of the vaginal vault; (b) 5 mL of 1% lignocaine injected at the 4 and 8 o'clock positions of the cervix and (c) no PCB. Pain scores during PCB, cervical dilatation and during and after suction evacuation were compared among the three groups. The sedation and satisfaction levels were also compared. There were no statistically significant differences in the pain levels during PCB, cervical dilatation and suction evacuation and in the satisfaction levels among the three groups. Patients with a lighter sedation level experienced more pain. In conclusion, PCB did not improve the pain levels during first-trimester suction termination of pregnancy after cervical priming with misoprostol and use of intravenous sedation, regardless of whether the local anaesthetic was injected into the cervix or the vaginal vault.
